By analyzing the problems of punching die design in production, using the method of punching force blanace, and propose solution using die block, it has the cretain reference function to similar parts die design.

The Calculation & Analysis of Blanking Force Applied to Thick Plank;

Using bevelled punch and step punch in blanking die, carried on the rational distribution to blanking force, reduced the blanking force well which the press equipment need, and the question of insufficient press equipment pressure was solved.

The blanking force calculation of blanking through inclined sheet metal is an outstuding subject.

Developing MDT6.0 with ObjectARX for quick and accurate stamping force calculation of dies;

After building a solid mould to make the mould s value of volume (or its value of mass) represent the progressive die s value of pressing force and its center of mass represent the center of pressing force, one can effectively solve the technical problem of the progressive die s pressing force and center of pressing force.

Through building upa solid mould, we are able to make volume value express pressing force and thecenter of mass express the center of pressing force, which easily and effectively solves the technical problem of seeking solutions of pressing force and centerof pressing force of the gang dies.
